Home routers supplied by ISPs can be compromised en masse
Specialized servers used by many ISPs to manage routers and other gateway devices provisioned to their customers are accessible from the Internet and can easily be taken over by attackers, researchers warn.
By gaining access to such servers, hackers or intelligence agencies could potentially compromise millions of routers and implicitly the home networks they serve, said Shahar Tal, a security researcher at Check Point Software Technologies. Tal gave a presentation Saturday at the DefCon security conference in Las Vegas.
At the core of the problem is an increasingly used protocol known as TR-069 or CWMP (customer-premises equipment wide area network management protocol) that is leveraged by technical support departments at many ISPs to remotely troubleshoot configuration problems on routers provided to customers.
